BAT54J

Nexperia · Schottky Diodes · SOD-323F

BAT54J from Nexperia, in a SOD-323F. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode; the marking bar indicates the cathode, and the mounting pad for cathode 1 cm² is used for the Ptot thermal rating (Ptot 550 mW at Tamb ≤ 25 °C).
2 A passive Anode of the Schottky barrier diode; the datasheet gives no pin-specific limit for this terminal beyond the device-level ratings (VR 30 V, IF 200 mA).

CAD (KiCad official)

  • Symbol: BAT54J
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: bat54j-etched.step / bat54j-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54j.step / bat54j.glb are the bare package body.
